A ATTORNEY June 23, 1931. P. M. NEJEDLY v CIGARETTE CORK TIPPR Filed Febi '7, 1930 2 Sheets-Sheet 2 ATTORNEY INVENT Patented June 23, 1931 UNITED STATES PATENT OFFICE PETER MARTIN NEJ'EDLY,v 0F BROOKLYN, NEW YORK, ASSIGNOR- TO AMERICAN MAJ- CHINE & FOUNDRY COMPANY, A CORPORATION OF NEW JERSEYy CIGARETTE CORK TIPPER This invention relates to an improved machine for applying covering material, such as cork tips, to wrapper material such as cigarette wrapper paper which may be used 5 in conjunction with continuous rod cigarette machines, its main obj ect being to produce a device suitable for operation at high speed, such'as 2,000 cigarettes per minute. A further object of' the invention is to provide an intermittently operating means for feeding the covering material and a Vcontinuously rotating knife for severing strips of the covering material of suitable length between the periods of feeding movement of the covering vision of means in connection with the means for applying adhesive to the wrapper material to automatically stop the application of adhesive to the wrapper material when the covering material feeding means fails to feed.` With these and other objects not specifically mentioned in view, the invention consistsin certain constructions and combinations of elements which will be hereinafterrfully described and then specifically set forth in the claims hereunto appended.

The cork strip, or other covering material, is fed from a reel through rollers rotating in an oscillating arm and passes under a ledger plate where it is cut by a revolving knife, the said arm being timed to swing backwards at the rate of the forward speed dur` ing the cutting period, so as to stop the relative motion of the strip during that'time without interrupting its actual continuous ,advance in the feed rollers. While thus held at rest in the cutting position, the forward end of the cork strip, or other covering material, restsv on the moving cigarette paper strip, or other wrapping material, passing over an idler roller at this point. Thel cigarette paper, before reaching this idler roller, is passed between a pair of adhesive applying rollers, one of which has a raised section of V-shaped formation, while the other has a corresponding indentation which carries the adhesive. Once in every revolution, thevpaper is pressedinto the adhesive on the indented surface of thelatter 5 roller by the raisedl portion of the former,

material. A still further object is the pro-V thus receiving areas or spots of adhesive such as paste at equal intervals alongits length. Above the aforesaid idler roller is mounted a continuouslydriven feed roller having a raised peripheral portion which makes contact with and engagesthe cork strip on the idler once in every revolution, so that the separate cut cork' tips are pressed upon the previously prepared areas of adhesive and are carried forward with the paper strip.

The improved covering materialv applying machine is provided with any automatic knockout device which disengages the drive ofthe adhesive applying rollers and permits the paper strip to pass freely between them, thereby preventing open paste from being carried by the paper onto the guide rollers and others parts of the machine when the cork strip fails to feed. sists of a cam-operated swinging arm carry-l ing an insulatedVV contact finger connected with the winding of an electromagnet,A so timed as to come down upon the cork strip end after each tip length has beenl fed and to remain in its down position during a portion of the cutting period. Whenv no cork has been fed, this finger makes 'contact with the metal support plate of the tips, thereby completing the electric circuit through the frame of the machine and energizing the electromagnet which thereupontrips the knockout lever.

In carrying the invention into effect, there is provided a machine for applying covering material to a wrapper material,` comprising means for feedingv and applying adhesive to the wrapper material, `means for intermittently feeding a continuous stripof covering material, meansl for severing suitable lengths of covering material, means for applying the severed' strips of covering ma- This knockout conterial to the adhesive portions of the wrapper material, and means for stopping the application of adhesive to the wrapper material when the covering material feeding means fails to feed.

In the best constructions, the cutting means comprises a continuously rotating knife operating on the covering material between the periods of feeding movement thereof, and the means forstopping the application of adhesive comprises a knockout device operative on the adhesive applying mechanism and controlled by an electrical device suitably connected tothe frame of the machine. l

These variousy means and parts may be widely varied in construction within the scope of the claims, for the particular machine selected to illustrate the invention is but one of many possible embodiments of the same. The invention, therefore, is not to be restricted to the specic construction shown and described. Y

Referring to the drawings, the frame 10 carrying the standsfll and 12 is adapted to be fastened to the frame of a cigarette` machine, or other support. `The roller 13 mounted on the shaft 19 cooperates with the rollers 14 and 15 mounted on the shafts 2O and 21, respectively, toy guide the cigarette paper or other material to be covered or tipped, as indicated at P, upwardly to the cooperating rollers 16 and 17 which are mounted on the shafts 22 and 23, respectively, Awhich conduct it to the roller 18 on the shaft y24 from whichY the material may be led to the tobacco feed of a cigarette ma# chine, if the device is to be usedin connection therewith.

The cork strip or other covering material C, which is supplied from a reel, Venters the tipper through a guide 25, fastened to a plate 26, which leads it to aV roller 27 turning on shaft 28. On the latterV shaft is mounted an arm 29 carrying on studs 30 and 31 the feedrollers 32 and 33 between which the cork stripis led after leaving roller 27, and which feed it to the ledger `plate 34. The arm 29 is connected to the eccentric pin 35 on shaft 36 by means of a link 37 attached to it by a pin 38 so that the -arm 29 swings back and forth on shaft 28 as shaft36 revolves, thus' periodically stopping the motion of the cork strip at the ledger plate during its `backstroke and advancing it at double the feed roller speed during its forward stroke. From rollers. 3 2, 33 the guide wires 39 lead the Ycork strip-through theV space betweenthe support, 40 and the plate'34, which actsy as ledger plate for rthe Vrotating knife 41,` onto :the plate' '42 from which the cut tip projects into the space between the paper rollers16- and 17 -and thusmeets the paper` strip P. j

The paper strip P, in passing between the rollers 14 and 15, has paste applied to itat properly spaced intervals. For this purpose, the roller 14, which rotates in the paste receptacle 43, has a depression 44 in which a small amount of paste is stored at each revolution, the high portion of the surface being wiped clean by a scraper 45 and side wipers 46, upon its emergence from the paste. Roller 15 has a corresponding raised portion 47 which presses the paper strip into the depressien 44 of drum 14, thereby transferring the stored paste to the paper at equally spaced spots.

The feed roller 17 jhas a raised portion 17 a which, when cooperating with roller 16 once in every revolution, clamps the cork tip and paper strip between it and roller 16, thereby attaching the tip C to the pasted portion of strip P and advancing the strip so tipped. Y y

To shaft 36, which is 'supported by stand 11, is attached the bevel gear 48meshing with bevel gear 49 on shaft 50 to which is fastened the knife holder 51 carrying the knife 41. The shaft 36, as well as all the other operating parts of the improved tipping mechanism, may receive their motion from a gear on the cigarette machine shaft (not shown) which meshes with the gear 52 on shaft 53 inbracket 54 attached to pedestal 10, the latter shaft also carrying the gear 55 meshing with gear 56 on stud 57. The gear 56 drives gear 58 on-shaft 20, on which is mounted the gear 59 meshing withgear 60 on stud 61. The shaft 20 carries a coupling 62 which drives shaft 63 and transmits the power to the paste rollers 14 and 15 through the meshing gears l64 and'65, respectively. The gear turns gear 66 on shaft 28 which carries the gear 67 driving gear 68 onstud 30. The large gear 66 turns the pinions 69, on stud 7 0and 71 on shaft- 36; the gear 69 drives gear. 72 on shaft 23 on which is mounted the feed roller 17.

VThe bracket 73 fastened to the frame 10 arm ismade to act as a knockout device for thepaste feed in case of ending or breakage of the cork strip, by holding it in its working position l(with thegear65 inmesh with 64) by means ofa catch 7 8` controlled by an electromagnet 7 9."` In the working position, with the' electrmagnetl unener'gized, the

catch 78 rests on a stop pin 80, andthe larm 77 is pulled against a shoulder at its end by a spring 81 attached to post 82 in stand 12. Vhen the electromagnet 79 is energized by the absence of a cork tip, the catch 78 is pulled up against the core 83 of the electromagnet, thereby giving free the end of Alever 77 which is then pulled against stop pin 80 by the spring 81, as shown in dotted lines in F ig. 1, thereby lifting the gear 65 out of engagement With gear 64 and stopping the paste feed so that the paper emerging from feed rollers 16 and 17 will carry no free paste to smudge the Working parts of the machine.

The electromagnet 79 receives its energy from aline circuit or from a battery 84, one terminal of which is joined by a Wire 85 to the magnet Winding 79, while the other terminal is connected by a wire 86 with a contact linger 87, Fig. 3, which is attached to an insulating blockSS, carried by a periodically swinging bell crank lever S9 pivoted on a pin 90 in lug 91 attached to bracket 92 on stand 11, and which rests on the cork tip C when the bell crank, which is controlled by a cam 93 attached toknife holder 51 on shaft 50, is in its down position. The bell crank is held in engagement with cam 93 bya spring 94 attached to stand 11. When the cork strip feed is continuous, the cork layer upon which rests the finger 87 acts as an insulation and prevents current from flowing into theelectromagnet, but When no cork strip is present, the linger 87 contacts with the metal support plate 42 Which, through the frame of the machine and through the wire 95, is connected to the winding of magnet 79, thereby completing the circuit and operating the catch. The paper then Will pass between rollers 14 and 15 without receiving paste, until the arm 77 is pushed back into working position, thereby allowing the catch 78 to drop back into holding engagement.' f
